At 13.13 hours on 6 Jun 1940, HMS Carinthia (Capt J.F.B. Barrett, RN) was hit aft by one G7e torpedo from U-46 west of Galway Bay. The Germans then observed how the ship turned apparently uncontrolled in circles and dropped depth charges from the stern. At 13.47 hours, a G7e coup de grâce was fired which missed and was answered by gunfire from the armed merchant cruiser. Endrass decided not to waste another torpedo and left the area because the burning ship was settling by the stern, developing a port list and the crew began to abandon ship.

HMS Volunteer (D 71) (LtCdr N. Lanyon, RN), HMS Wren (D 88) (LtCdr F.W.G. Harker, RN), HMS Berkeley (L 17) (LtCdr H.G. Walters, RN), HMS Gleaner (J 83) (LtCdr H.P. Price, DSO, RN), HMS Brigand (W 83) and HMS Marauder (W 98) (Lt W.J. Hammond, RNR) were sent to assist HMS Carinthia and she was taken in tow the next day by the latter, but foundered about 34 miles east of Bloody Foreland at 19.00 hours. Two officers and two ratings died in the attack.
